Organocatalytic asymmetric desymmetrization of 4,4-disubstituted cyclohexadienones via an intermolecular Diels–Alder reaction†
Abstract
Asymmetric desymmetrization of 4,4-disubstituted cyclohexadienones via a chiral phosphoric acid-catalyzed enantioselective intermolecular Diels–Alder reaction is developed.
